Opera does not provide its own malware blacklists. The list provider that has blocked that website is Yandex, and they will have blocked it because they detected malware on the site.

You can see which list provider has detected the malware by clicking the “Why was this page blocked?” link on the warning page in Opera. You can report it to that list provider if you believe it to be a mistake.

Note that some websites may display fake virus warnings, hoping to convince you to download and install malware disguised as an anti-virus product, or hoping you will contact them and follow malicious instructions. If a website tells you that you have a virus, the warning is usually fake. If you think that your phone has a virus, you should use reputable anti-virus and anti-malware products to remove it.

It sounds like there may be an unwanted application installed on your phone, which is opening the unwanted pages in your browser. You will need to work out which app this is and remove it. You should also use reputable anti-virus and anti-malware products to remove any malware which may have been installed.

Your website is blocked by Netcraft, not Opera itself. We use their blacklist to protect Opera users from fraud attempts. This will also affect your site in any other browser where the user has installed the popular Netcraft toolbar.

Note that there are a number of ways a legitimate site could contain fraudulent content:

The server may have been hacked and malware or fraudulent content was installed on it. This is sometimes hidden in a folder that does not appear on FTP or with common command line tools (e.g. there is a common rootkit that hides things in a folder called /.sk/ and then modifies the command line tools so that they never show it).

If the site includes scripts, images, iframes, or stylesheets from other websites, any of those could have been compromised and could, therefore, deliver fraudulent content when used as part of the site.

Netcraft will check for these cases when they scan the site, or before removing it from their listings. Netcraft also use a heuristic to detect newly discovered sites that are at high risk of being used for fraud, even if those sites are in fact clean. This could be what made them list your site highly in their risk rating.

Please follow up with Netcraft if your site continues to be blocked by their fraud listings.

If one of Opera’s list providers has identified malware on a website, but other browsers have missed it, that is a good thing for Opera, not a bad thing. Other browsers have failed to detect it.

You can see which list provider has detected the malware by clicking the “Why was this page blocked?” link on the warning page in Opera. You can report it to that blacklist provider if you believe it to be a mistake.

Unfortunately, you have reported this problem to the wrong company. We do not own the websites that you visit (except opera.com) and we cannot control your accounts on those websites. If you are having problems with your account on a website, please contact the owners of that website.

Unfortunately, this is a problem with the Tubidy website, not with the Opera Mini browser. Perhaps one of their scripts has an error or there are other issues. There is, therefore, nothing further we can do about this problem. The website is choosing to redirect you to the adverts, and they cannot be blocked by regular ad blocking.

We have informed the website owners of the problem and hope they can fix their website soon.

Unfortunately, you have reported this problem to the wrong company. We cannot control your Facebook account nor the problems that occur on Facebook. If you are having problems with your Facebook account, please contact Facebook.

Note that the Facebook website works best if you disable Extreme data savings mode in the Opera Mini menu.

Opera does not maintain its own phishing, fraud, or malware blacklist. The blacklists are provided by several partners, such as PhishTank and Netcraft for phishing and fraud, and AVG and Yandex for malware.

If you feel that any of these have failed to recognize a fraudulent or malicious website, you can contact the companies mentioned above to have the URL added to their blacklists (after they have tested the sites). Opera will then use the updated blacklists as soon as the website is added to it. You can contact each of the companies here:

You are seeing the “Fraud warning page” because the page you want to visit is listed as dangerous on some blacklists. Opera does not maintain its own phishing, fraud, or malware blacklist. The blacklists are provided by several partners, such as PhishTank and Netcraft for phishing and fraud, and AVG and Yandex for malware.

If you think that the blacklist provider has made a mistake, you can click the “Why was this blocked?” at the bottom of the fraud warning page. link to see which blacklist provider has identified the malware. You can then contact that blacklist provider to inform them of their mistake.
